Zenith Security Co. lists eight Union Essentials door locks and latches, all under door locks and latches. Prices are shown openly.

Union locks we list

• 3 lever sash locks — Y-ES-SL in chrome or brass, 2.5 inch.
• 3 lever dead locks — Y-ES-DL in chrome or brass, 2.5 inch.
• Tubular latches — Y2600 in brass or zinc, 2.5 inch and 3.0 inch.

Three lever locks are generally used on internal doors; for an external door, check what your insurer requires before choosing a lock. If you are adding access control to an existing door, the lock already on it usually decides what is possible, so tell us what is fitted and we will work back from that. See access control door locks and Yale for other options.
